• We’ll need a “Duty” parameter that controls the duty cycle of the LFO module’s waveshape.
• Finally, we’ll want (though we don’t need) a “
Sweep” monitor that monitors the output of the LFO
module.
We’ll hook each one of these up and then use the VSigfile Specifier Display window to set all of the various
specifiers correctly.
Strength
The first “parameter adjuster” we’ll want to add is a
knob module
(from the “Interface” group). Go ahead and
add it, and connect it to the microdelay module
as shown.
Then double click on it to enter the VSigfile Specifier
Display window. To the right is how we’d like to set
everything and here’s why:
• We set the module’s name to reflect its purpose.
Adding the “1” at the end ensures that when we
copy this module later, the copied version is
incremented properly.
• The menu statement is what will appear on the
menu page. We write “4.1” because we want the
value to take up four spaces no matter how many
digits there are and because we want only one
decimal point of precision.
• Because this knob module will be connected to
a menupage module and not to the head module directly, the 8 char name is left blank (it would serve
as the
SOFT KEY title if the module were connected directly to the head module).
• The min is set at zero corresponding to no modulation at all.
• The max is set at “49.9” because we set our maximum delay time to 50 milliseconds and we set the
delayamt to “0.1." We don’t want the user to specify a
Strength that is greater than what the
microdelay module is set up to deliver!
• We set the resolution to “0.1” so that a spin of the
KNOB results in a reasonable change in the
Strength’s value.
• We set the default value at “10” because 10 milliseconds is a pretty standard flanger strength.
Feedback
Add a percentknob module and connect its
control output to
amp2 on the mix module. Then
double click on it. Change the specifiers as shown to
the right.
• The mix module’s control inputs accept a value
from -1 to +1
(negative values invert the phase of the applied
signal)
. Recall that the percentknob
module’s output will be 1/100th that of its
displayed value. Thus we can display the
feedback as a percentage and still get the
appropriate fractional control output.
